Fentrend is a window and door marketplace with a mission to lower greenhouse gas emissions one building at a time. We help architects and builders navigate the opaque process of identifying the most energy efficient windows and doors for less money.

No, we’re independent and always will be. What that means is that we represent multiple window companies and have no bias to recommend one over another. For us, it’s important you find the right solution for your needs, without overpaying. When window companies compete for your business, you win.

What is your service area?

All of U.S. and Canada.

Is it cheaper to buy windows through Fentrend?

Our job is to help you find better windows, for less – and without using “car salesmen” tactics. We believe we accomplish this by:

Having the most comprehensive network of window suppliers from a single point of contact.

Offering you an easy way to find and compare your options.

Provide a competitive environment for window suppliers to offer the best product at the best price.

At the end of the day, we believe you win by offering you access to the global window market, and providing you tools to make informed and unbiased decisions.

Overheard

“Fentrend will solicit and compile proposals from various manufacturers in an comparative format making it easy to analyze data, like frame u value, condensation resistance, etc. When manufacturers’ relative pricing is not always easy to access and compare, this service is hugely beneficial during the design phase….Frankly, I can’t believe this service wasn’t available, as far as I know, before discovering them. Such a great idea.”

“Simplified and expedited the process as well as introduced us to options we did not know existed.”

“Fentrend was great in sourcing window reps and getting very competitive quotes for us. This is a task that would normally take up project management time and allowed us to allocate that time to other start up tasks which was great. It was nice to see new European manufacturers to the American market for Passive house windows…without Fentrend I don’t think we would have found them otherwise.”

“My biggest comment would be that we receive bids or proposals from vendors quite often, and the laborious work required to vet these people, to level their scope of work, to make sure they are installing or have another vendor capable of doing so and providing the necessary warranties is a lot to deal with, but something that is absolutely required. I like the companies idea, you guys work hard, and the presentation was great.”
